{2} And when they saw it, they all murmured, saying, That he was gone to be guest with a man that is a sinner.

(2) The world forsakes the grace of God, and yet is unwilling that it should be bestowed upon others.

People's New Testament

19:7 They all murmured. How often these complaints of Jesus stooping down at the company of sinners are recorded! Now, however, the crowd expected that at Jerusalem his kingdom would be proclaimed, but here he is the guest of the chief agent of the oppressive Roman tribute! Had Christ sought popularity he would never have gone with Zacchaeus.

Wesley's Notes

19:7 They all murmured - All who were near: though most of them rather out of surprise than indignation.

Jamieson-Fausset-Brown Bible Commentary

7. to be guest-or lodge: something more than "eating with" such (Lu 15:2).

a sinner-that was one but a minute ago, but now is not. This mighty change, however, was all unknown to them. But they shall know it presently. "Sinner" would refer both to his office, vile in the eyes of a Jew, and to his character, which it is evident was not good.

Matthew Henry's Concise Commentary

19:1-10 Those who sincerely desire a sight of Christ, like Zaccheus, will break through opposition, and take pains to see him. Christ invited himself to Zaccheus' house. Wherever Christ comes he opens the heart, and inclines it to receive him. He that has a mind to know Christ, shall be known of him. Those whom Christ calls, must humble themselves, and come down. We may well receive him joyfully, who brings all good with him. Zaccheus gave proofs publicly that he was become a true convert. He does not look to be justified by his works, as the Pharisee; but by his good works he will, through the grace of God, show the sincerity of his faith and repentance. Zaccheus is declared to be a happy man, now he is turned from sin to God. Now that he is saved from his sins, from the guilt of them, from the power of them, all the benefits of salvation are his. Christ is come to his house, and where Christ comes he brings salvation with him. He came into this lost world to seek and to save it. His design was to save, when there was no salvation in any other. He seeks those that sought him not, and asked not for him.
